Layla Elkassih Separation of the Components of a Mixture Lab Partner: Satan’s pubes. Date Performed: 9.28.2015 Chemistry 1411 Separating the elements of a mixture can be done through decantation, extraction, and sublimation. This experiment starts by practicing the sublimation process by heating the mixture: NaCl, NH_4 Cl, and SiO2. Through sublimation, the mass of NH2Cl can be found. Then by extraction, water, the mass of NaCl can be found; decant the water, extracting the NaCl from the mixture. Finally, the third element remains (SiO2). Which enables he/she to calculate the percentage of composition for each element in the original mixture. In order to perform this experiment, he/she will need the following materials: One Apparatus One Glass stirring rods One Balance One Hot-plate One Bunsen burner and hose One One Tong One Watch glass One 50-100 mL graduated cylinder Two Evaporating dish And the following chemicals: H20 (water/ 55.5 mol/L) and the unknown mixture of NaCl, NH_4 Cl, SiO_2. (Sodium chloride, ammonium chloride, and silicon dioxide). Procedure: Zero-out the balance and place an empty evaporating dish on the scale. Weigh and record the mass. Zero-out the balance and place a watch glass on the scale. Weigh and record the mass. Place the evaporating dish onto the scale and zero-out the balance. Pour three grams of the NaCl, NH_4 Cl, and SiO_2 mixture into the dish. Heat the mixture: Attach the gas hose to the bunsen burner, inside the fume
